Embodiment 1

[0044] An electric vehicle with a modular battery comprising:

[0045] A car body 1, which is provided with a battery pack 2;

[0046] The battery pack 2 includes:

[0047] The central battery unit 3 is detachably connected to several modular battery units 4 respectively.

[0048] Described modular battery unit 4 comprises: battery case 8, and its built-in several rechargeable batteries 14; Described rechargeable battery 14 is provided with foldable rechargeable battery handle 16; The battery case loam cake 9 ( According to needs, the battery box and the upper cover can be designed as one or separate type), and the upper cover handle 10 is arranged above it; the battery unit positioning structure 7 for connecting with the automobile body 1 is located in the battery box 8 superior. The battery box loam cake 9 is provided with some loam cake locating columns 11, and the rechargeable battery 14 is provided with a battery locating hole 17 which is matched and connected with the...

Embodiment 2

[0062] As a new embodiment or as a supplement to Embodiment 1.

[0063] This embodiment mainly solves the battery life and intelligent management problems of electric vehicles. The power battery of the new structure electric vehicle adopts a small modular battery unit. The battery unit is composed of a group of central battery units 3 and several groups of modular battery units 4. The central battery unit 3 uses a whole battery, or it can be combined with a modular battery. Unit 4 is composed of multiple batteries, and each battery adopts a miniaturized and standardized structure. A certain number of batteries are connected in series to reach the required voltage as a basic battery unit, and then several basic battery units are connected in parallel.

[0064] The central battery unit 3 is used as the core unit, and is fixed in the car body 1 as a single battery box, which can independently drive the whole vehicle. The modular battery unit 4 can be placed at the front, the rear...

Abstract

The invention discloses an electric vehicle with modular batteries, and belongs to the field of electric vehicles. Comprising an automobile body provided with a battery pack and a battery management system; the battery pack comprises a central battery unit which is detachably connected with a plurality of modular battery units; and each modular battery in the battery pack is provided with a chip and / or an RFID-like tag with a unique identity label and a charging and discharging frequency recording function. Endurance can be achieved by increasing or replacing the modular battery units, and the endurance time of the battery is effectively prolonged through the heat preservation layer and the heat preservation medium; the problem of mileage anxiety is solved, and the battery of the electric automobile using the modular battery is standardized and convenient to replace; an energy storage power supply can be used; the peripheral thermal insulation design can prevent the power consumption of the battery from being too low in cold seasons in winter, so that the automobile can be started at any time; the battery management system is in two-way communication with the modular battery and the cloud server, data are interacted in real time, the source of the modular battery can be checked, the destination of the modular battery can be tracked, and the state of the modular battery can be monitored in real time.

Description

technical field [0001] The invention belongs to the field of electric vehicles, in particular to an electric vehicle with a modular battery. Background technique [0002] At present, the integration of automobiles and related technologies in the fields of energy, transportation, and information and communication is accelerating, and electrification, networking, and intelligence have become the development trend and trend of the automobile industry. Pure electric vehicles have become the mainstream of new sales vehicles, vehicles in the public domain are fully electrified, fuel cell vehicles are commercialized, highly autonomous vehicles are applied on a large scale, and charging and swapping service networks are convenient and efficient. At present, fuel vehicles are still the main vehicles, so there is a huge space for the development of electric vehicles, and the main restrictive factor affecting the development of electric vehicles is the power battery. Short battery lif...
